Are you sure that your DBMS is properly configured to guarantee optimal query performance, ensure data integrity and enforce proper security? ensquad can help with these and more.

We can help to properly configure and tweak the DBMS settings to best accommodate your business requirements. Data is one of the most important assets of a company and one of its critical components, are you sure to have a proper backup strategy? When was the last time a backup was made? Which data was backed up? How long will it take to restore data? It’s also very important that every user is managed correctly ensuring proper role assignment and making sure to limit unwanted actions.

A database must be designed according to your company’s needs, but not every design is created equal. We can show you the proper way of designing a normalised database intended for the day-to-day running of a business. This can also involve changing your existing database to one which is more suited to your needs. The entire process is explored from the initial sketch to the database plan (Entity Relationship Diagram – ERD), and finally to the actual implementation in SQL.

Having designed the database, we can also show you how to populate it using your own data and retrieve data based on your business needs.

End of month is approaching and you want to find the total sales per month; a simple SELECT statement might get you the data that you need, but sometimes more than that is required. What if you need to add a 5% bonus to the salesperson who sold most Piña Colada during the sizzling summer months of 2017?

We offer advanced SQL query training that allows for data to be retrieved from complex database structures, generating summaries and statistics, or even working with different file formats.

Every day, your business generated substantial amounts of data which accumulates very quickly over periods of time. This data is usually stored in a database especially created for the day-to-day operations of a business. This historical data although valuable is never used, rendering it dormant, and over time, it can also degrade the database performance.

What if you can keep the operational performance as if it was the first day AND get value from the historical unused data? To do so, a specially designed database (data warehouse) must be used.

Do you have substantial amounts of business-generated data that is dormant and never used? Do you want to know the diverse types of customers just by analysing their purchases?  We can help you with that.

We can show you how to extract data from your existing sources such as spreadsheets, relational databases and data warehouses. This will then lead to a process of understanding this data (data exploration) and data cleaning (removing any inconsistencies and prepare it for data analysis).

When thinking about data security, many believe that the latest technology in access control, antivirus and firewalls are enough to protect their valuable data. While installing security patches and updates on a correctly configured system is vital, employees are an equally important aspect to keep in mind. Data breaches are often the result of a well-meaning employee who clicks on a phishing email, gives out information, shares a password or any other mistake. Security should not be a tug-of-war between system administrators and the rest of the employees. People are creative and will find ways around restrictions to get their job done, training is key!
